Hi, I recently added 3 new servers to Ceph cluster. These servers use the H740p mini raid card and I had to install the HWE kernel in Ubuntu 16.04 in order to get the drives recognized. We have a 23 node cluster and normally when we add OSDs they end up mounting like this: /dev/sde1 3.7T 2.0T 1.8T 54% /var/lib/ceph/osd/ceph-15 /dev/sdj1 3.7T 2.0T 1.7T 55% /var/lib/ceph/osd/ceph-20 /dev/sdd1 3.7T 2.1T 1.6T 58% /var/lib/ceph/osd/ceph-14 /dev/sdc1 3.7T 1.8T 1.9T 49% /var/lib/ceph/osd/ceph-13 However I noticed this morning that the 3 new servers have the OSDs mounted like this: tmpfs 47G 28K 47G 1% /var/lib/ceph/osd/ceph-246 tmpfs 47G 28K 47G 1% /var/lib/ceph/osd/ceph-240 tmpfs 47G 28K 47G 1% /var/lib/ceph/osd/ceph-248 tmpfs 47G 28K 47G 1% /var/lib/ceph/osd/ceph-237 Is this normal for deployments going forward…or did something go wrong? These are 12TB drives but they are showing up as 47G here instead. We are using ceph version 12.2.13 and I installed this using ceph-deply version 2.0.1.
